The pier bracket is then bolted to the footing with 1/2” diameter x 5-1/2” long anchor bolts to secure it in position. Vertical alignment should be verified to ensure the drive stand assembly frame is plumb prior to driving each pier section. They manufactured …. In granular soils helical pile capacity is dependent on effective overburden pressure. RS5500 HCP Tension/Compression only, Cap, New Const. A careful inspection should be made, making sure the face plates have continuous bearing across the entire piece. Note: Do not use any damaged or leaking hoses or hydraulic equipment. Extension– A pile section without helical plates. The pier post brackets are positioned and fastened with the washers and nuts provided with the anchor bolts. Used for a variety of applications for lighter structures. As a result of their true helical shape, the helices do not auger into the soil, but instead screw into it with minimal disturbance. Load-testing a helical pile is far simpler than it sounds. HELI-PILE ® is a pioneering provider of high strength helical pile deep foundation support and anchoring systems. A. The purpose of a helical pile is to provide foundational support for structures of all types and sizes. When the helical pile is laterally unsupported (very loose/soft soil, liquifiable soil, water and … SS175 Tension/Compression, Cap, New Const. Helical Piles, also known as Helical Piers or Helical Anchors are a type of deep foundation system used for over a century to help stabilize structures in soils that are prone to settlement. 1-516-315-8591. If the lowest-to-highest shut-off pressure sequence is followed, the system pressure should always be lower than the next shut-off pressure. The round shaft pipe helical pile provides a much wider diameter than most square shaft piles. What Do Helical piles Do? Align the bracket centerline directly with the hole through the footing and carefully mark the locations of the anchor bolts on the mounting face of the structure. RS3500 Full Tension/Compression, Cap, New Const. The loading of the pile is calculated as it is installed, and additional extensions are added on until the required loading is achieved. It is recommend that a registered professional engineer conduct the design work. RS2875 HCP Full Tension/Compression, Cap, New Const. After all, piers are mechanically locked off and the lifting heads and hydraulic lifting system are removed, backfill the excavations with the excavated soil. With our superior patented Inertia Welding Technology, we provide the strongest piles in the industry. Helical piers also known as helical piles, screw cylinder anchors and helical foundations started to be used in 1836. The first extension is bolted to the lead section and additional extensions are bolted on until the helical pile reaches the desired torque and/or depth. First reduce the overall system pressure to below the lowest individual pier shut-off pressure using the valve at the pump. RS5500 HCP Compression only, Cap, New Const. SS225 Tension/Compression, Cap, New Const. Helical Piles 101, is intended for the people to understand the basics of Helical Piles, where helical piles can be used and how helical piles can help save them money. Note: Ensure the pier bracket is secured during the installation of each pier section. We have the facility to design and fabricate special orders as well, meeting any shaft diameters your project calls for. Tied to reinforcing bars prior to concrete being poured. Just like old-fashioned pile-foundations, helical piles (also referred to as screw piles, helical piers, helical anchors, etc.) Anchor bolts hold bracket to footing. SS5, SS150, SS175, RS2875.203, RS2875.276, RS3500.300, Brackets, Micropile Attached to helicals for moorings and float docks. The height of the pile above grade is measured. Helical Piles The helical pile system is a segmented deep foundation system with helical bearing plates welded to a central shaft. Cut the section so that after the lift is complete the top of the pier cap will be about 1/4″ below the bottom of the lock off pins. Helical piles are installed by rotating the shaft of the pile. Chance Foundation Solutions is a proud member of the Hubbell family.
